Fine-grained tree-species segmentation in UAV RGB imagery using parameter-efficient segment anything adaptation

Aug 2026 · Journal of Forest Research · Vol 37 · 1 citation · 39 references

TL;DR

HDP-SAM is proposed, a prompt-free and parameter-efficient SAM adaptation framework for UAV forest imagery that leverages SAM’s pretrained mask priors and structural representations to enhance crown-level coherence and demonstrate the effectiveness of HDP-SAM for fine-grained tree-species segmentation in complex UAV forest scenes.

WetVeg-2mm: An Ultra-High-Resolution UAV Dataset for Riparian Vegetation Semantic Segmentation

Fine-grained mapping of riparian vegetation is important for ecological monitoring, invasive species control, and ecosystem restoration. However, riparian plant communities often exhibit fragmented patches, broad transition zones and high visual similarity among classes, making stable species-level segmentation difficu...

Unsupervised Class-Guided Synthetic-to-Real Domain Adaptation for Plot-Level Forest UAV LiDAR Semantic Segmentation

Semantic segmentation of forest point clouds is pivotal for automated forest inventory but is severely constrained by the scarcity of high-quality real-world annotations. Although synthetic forest point clouds provide a scalable alternative for training, models trained on synthetic data often suffer from pronounced per...
